2019/12/13

Note: Lubricate Tooling (B) for easier removal of the camshaft. Lubrication also prevents
damaging the camshaft lobes and the camshaft bearings.
6. Use two people to remove camshaft (7). The weight of camshaft (7) and the camshaft gear
is approximately 34 kg (75 lb). Carefully remove camshaft (7) from the engine. Support the
weight of the camshaft during removal.
Note: Rotate the camshaft during removal. This action will prevent the camshaft from
binding in the camshaft bearings.
Installation Procedure
NOTICE
When installing the camshaft, make sure the number one cylinder is at
top center of the compression stroke with the timing bolt installed in
the flywheel. The camshaft timing is very important. The timing mark
on the camshaft drive gear must line up with the timing mark on the
idler gear. Refer to the Specifications Manual for more information.

Note: Ensure that camshaft (6) and Tooling (B) are clean. Apply clean engine oil to the lobes and
journals of camshaft (6) and Tooling (B).
Note: During installation of camshaft (6), rotate the camshaft in both directions in order to prevent
binding in the camshaft bearing bores.
1. Install camshaft (6) in the reverse order of removal.
a. Ensure that the timing Marks (X) on the idler gear aligned with the timing marks on
the crankshaft gear and the camshaft drive gear.
